You can be against it all you want but that doesn't mean it's going to matter IRL. The state of the world is that anyone with a large amount of data like this is using it to build models so they can profit and/or enforce. Even if they say they're not doing it, they're still doing it. Or someone with access to that data is doing it.

Crying about the feds/DMV doing facial rec training is low hanging fruit. Obviously they're going to be doing it along with every other government on the planet with the resources to do it. TBH there's nothing inherently malicious about it, since them having the data they're using is part of you having citizenship/identification in that country. The real malicious ones are the corporations contracted by said government to do the exact same thing except they're doing their own data collection through huge networks of privately owned security cameras.

The only way to avoid this is to go live in the woods and never come out. Any show of transparency or opting out of any of this would just be theater for you. It's being done, has been done, and will be done without your consent or knowledge.
